Signal pays more for delivering verification SMS during sign-up, than for all other infrastructure (except traffic) combined. Wow, that sounds excessive.

I really wonder why it’s so expensive to run. I always hear things about scaling but I used to run a top 500 alexia website and it was just a php app running on a mutualized offer for $5/month. Lots of manual caching though but still.

My wild guess is that either the stack is not really optimal (last I heard it was java) or they do other costly things at scale (sgx?)

You can't send an sms yourself like you can an email. Instead of setting up a server, you have to work with a telco provider (an aggregator specifically). Any SMS service eventually hands off to one of these. Many SaaS SMS providers are just frontends for legacy telco services. They charge insane fees because they can, that is all there is to it.

Sending mass email is still difficult. Its probably easier to pay a provider than set up and establish reputation for yourself. But they don't charge near the rates. Last time I compared rates it was something like 10x-100x to send an sms compared to an email, but it has been a while.

Maybe they should flip it on its head - get a thousand? Ten thousand? numbers that can accept SMS and tell people to "text 473843 to this number" to verify.

It's usually even more expensive to support receiving messages than sending them, beyond keywords like Unsubscribe. If you want any sort of threading its going to be extra. Also its extra for dedicated shortcodes. When you get an SMS from a random shortcode, there might be multiple companies using that code, but they mix the pools enough that its unlikely you will receive two messages from two companies from the same code. Also shortcodes are usually country/region locked. So if you want to international support, you need to buy shortcodes in multiple regions, and different regions have different telco laws. On top of that, provisioning is very manual compared to the modern cloud.

I supported a marketing platform for a while, and it was so much easier to send an email than an sms.
